Thank you, kind sir I bought this house well over 20 years ago & the front bar door has this type of lock. For a long time no one knew anything about what it was. And unfortunately, to this day, I've never had a key! But now I'm dead set on getting a key. Thanks to you at least now I know so much more about the lock, mainly, how to get it out! :D I'll take it to a locksmith to see if it's possible to be rekeyed/replaced... (I'll start with calling 1st, but I'm sure they'll say they need to see it--BIG service call, right? Not! :) I'm fairly sure some years ago a handyman told me a regular deadbolt won't fit, for both configuration, And the narrowness of the door. :( I know this is an old video, but if you happen to see this comment, I'd welcome any suggestions. From anybody! :) (And I'd rather not have to pay $$$ for another door, and then pay $$$ for install, hint, hint :)
Mr @craiglist474, if the lock is functioning well and your problem is just to have a working key, just take out the Mortise cylinder, and bring it to a nearby lock shop, they can easily make a key for it. To remove the Mortise cylinder---take out the cover by unscrewing the two screws of the face plate.(that is located where the bolt is projecting.) you can see two tiny holes (aligned with the mortise cylinder) take a small philip screwdriver, insert it in the position side of the mortise cylinder, the screwdriver will end up at the head of the retaining screw of the mortise cylinder, unscrew (or loosen it up.). you can turn the mortise cylinder once its free from the retaining screw. remove the mortise cylinder, and visit the lockshop for an easy rekey. hope it helps.
@@yononable Thank you! After reading your reply, I'm actually standing at the door looking at the lock as I type this. Thank you for the instructions. And for the motivation and encouragement!
the simplicity of the mechanics, the robust construction and the very durable mechanical parts of this sargent 7704..set this type of lock apart from other mortise locks..however the newer sargent locks with lots of features like the 8205.. i observed not quite as durable than the older type.
Hi I'm a locksmith and I came across two of them over the last two months, to my I couldn't get the outer stop come out. This got locked in her apartment two times the building security had to open the door from the other side. Then a day ago I get a service call for a condo key stuck wont turn. Tried the under the door tool not turning. The key cuts stuck at 5:00 position . Last resort drill out mortise lock, which I hate doing. Started small work my way up that darn lock said kiss my *** broke about 4 drill bits. And told my new step drill the same thing. Now is 0100 - 0130. The family and friends standing in the hallway the whole time, the last condo next to the fire door. Which they had open to cool off, little did it help, the father is a five year kidney receiver and his medicine and car keys were locked in the condo they call around to get his meds one in the morning. But one thing I did I made sure as hell to get that stubborn sob out the door, took a while got my vise grip on it and screw it out. And guess what no matter how hard I tried could not get the bolt to come back into door. Do 02:15 we decided to stop and come back the later in the morning, 09:00. They got a cab and was lucky to get a hotel room so early in the morning, and it was a state holiday. Ok sorry. I will share how I got the door later that morning. Which was yesterday.
hi tim that was some sort of a frustrating experienced..it happens on all of us locksmith's once in a while...i know how strong these sargent locks are..but...there are always the un expected...let me guess.. since you already took the cylinder out, (am i right?)still the bevel bolt wont retract...wouldt it be that..the bevel bolt and the pulling bolt been dis engaged fron each other? leaving the bevel stuck in the latch catch of the door jamb?
@@yononable Thank you. Now I'm looking for a replacement lock assy. New or used. I know the 77 are no longer made, any idea where to find the same lock?
Tim, i think it like looking a needle in a haystack. if i am in your place..i'd rather fabricate (if that is possible) to replace the part that was cut off. i did a lot of modification and fabrication of parts by hand..sometimes i used parts from other mortise locks and just reshape it. regards.
Thank you, kind sir

We don't have the key, is there another way to unscrew the cylinder?
Thank you
